AUTOMOBILE LIFTING JACK.

Application filed February The invention relates to jacks tor automobile wheels, and has tor its object to provide a device ot this character which may be easily applied to an automobile wheel, and the wheel rotated slightly until the device is in engagementwith the ground below the whceh and when in such position the device will maintain the tire of the vheel out of engagement with the ground, thereby allowing the tire and demountable r m to be removed trom the wheel telly tor repair or replacement purposes, thereby obviating the laborious operation ot handling camber some jacks as at present constructed.

A turther object is to provide a wheel aclt comprising an L-shaped' member engaging the inner side ot a telly and having one ot its arms engaging the outer side of the telly, a downwardly extending arm hingedly connected to the l.-shaped member and engaging the other side of the telly and a downwardly and outwardly extending integral arm carried by the hinged arm and extending under the tire in a space relation thereto.

A turther object is to provide a downwardly and outwardly extending arm with a recess which engages and receives the inner side of the clincher flanges ot the rim tor bracing the curved arm, and to provide the curved arm with a reinforcing flange tor bracing the same when the arm is supporting the wheel spaced from the ground and receives the weight ot the vehicle.

A turther object is to proportion the hinged arm and the other arm engaging the sides of the telly whereby they will engage the clincher flanges and brace the arm and prevent side pivotal movement when the arm is moved into engagement with the ground upon rotation ot the wheel.

A further object is to provide a removable bolt extending transversely through the arms ot the device and the telly tor rigidly securing the device to the wheel.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set torth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing Figure 1 is a view elevation of a conven- 20, 1926. Serial No. 89,707.

tional torm ot automobile wheel showing the jack device applied thereto.

Figure 2 is a vertical transversely sectional view taken on line 2-2 of Figure 1.

Figure 3 is a perspective view ot the device.

Referring to the drawing, the numeral 1 designates a conventional torm ot automobile wheel, 2 the telly thereof and 3 the spokes. Disposed on the telly 2 is a conventional form of demountable rim 4 having clincher flanges 5 which hold the tire 6. The jack comprises a plate 7 which engages the inner side of the telly 2, and which plate has its outer end provided with a right angularly disposed arm 8 which engagesthe outer side ot the telly 2, and the'outer clincher flange 5 at 9, and which engagement at 9 braces the device and prevents pivotal twisting of the same on the bolt 10 when the wheel is rotated tor positioning the device below the wheel. Hingedly connected at 11 to the inner end of the plate 7 is an arm 12, through which the bolt 10 is threaded at 13 and which arm engages the clincher flange 5 and additionally prevents a twisting movement of the device when the wheel is rotated. Extending downwardly and outwardly in spaced relation to the tire 6 is a ground engaging arm 14, the lower end of which is relatively wide so it will not imbed itself in the ground and by being spaced from the tire 6 it is obvious when the same is disposed beneath the tire by the rotation of the wheel the operator can easily remove the demountable rim 4: in the usual manner by loosening the clips 15. Arm 14 is provided with a reinforcing rib 16 which is sufliciently strong to brace the arm 14 and prevent bending ther-eot.

In applying the device the plate 7 and the arm 8 are placed in engagement with the telly, then the arm 12 is moved on its hinging point into engagement with the inner side of the telly 2 which will move the curved arm 14 into position where it will extend around the tire 6 in spaced relation thereto, and atter which the bolt 10 is placed in position. It will be seen by providing the hinge 11 a close fit is obtained on the telly, and at the same time the curved arm 14 is allowed to be placed in position and the arms 8 and 12 in engagement with the clincher flanges 5.

From the above it will be seen that an automobile wheel jack is provided which is simple in construction, the parts reduced to a minimum, and one which may be'easily and quickly applied to a tire. The upper end of arm l l is provided with a transverse recess 17 which receives the inner clincher flange 5 and is thoroughly braced by said clincher flange, thereby adding to the rigidity of the structure.

The invention having been set forth what is claimed as new and useful is 1. The combination with an automobile wheel telly, a demountable rim mounted on said telly, a tire carried by said dcn'iountable F rim, of a detachable jack carried by said telly, said jack comprising a plate engaging the inner peripl'iery of the lolly, an art Ct rried by said plate and engaging one side of the telly, an arm hingedly connected to the the plate and engaging the other side ot the telly, ends of said arms engaging the demountable rim, a removable bolt extending through the arms and the telly, and a downwardly and outwardly curved arm carried by the hinged arm and terminating below the tire in spaced relation thereto.

2. The combination with an automobile wheel telly, a demountable rim carried by said telly, a tire carried by said demountable rim, clincher flanges carried by said demountable rim and extending beyond opposite sides of the telly, of a jack, said jack said telly, a tire carried by comprising a plate engaging the inner periphery of the telly, arms carried by said plate and engaging opposite sides of the telly, one of said arms being hingedly connected to the plate, a bolt extending through said arms and the felly, said arms engaging the demountable rim, an arm carried by the hinged arm and curving downwardly and outwardly in spaced relation to the tire and teminating beneath the tire, a reinforcing rib carried by said curved arm, said curved arm having its upper end provided with a recess in which one side of the demountable rfm is disposed.

3. The combination with an automobile wheel folly, a demount-able rim carried by said rim, of a jack, said jack comprising a Usshaped member in which the telly is disposed, a securing bolt extending through the arms of the U shaped member and the telly, one of the arms of the U-shaped member being hingedly mounted, said hinged arm of the U- shaped member being provided with a curved arm extending downwardly and outwardly in spaced relation to the tire and terminating under the tire.

In testimony whereof we aflix our signatures.
